When you try to start Exchange Management Shell (EMS) or Exchange Management Console (EMC) on a computer that is running Microsoft Exchange Server 2010, you receive the following error message:
Connecting to remote server failed with the following error message: The WinRM client received an HTTP server error status (500), but the remote service did not include any other information about the cause of the failure. For more information, see the about_Remote_Troubleshooting Help topic. It was running the command 'Discover-ExchangeServer -UseWIA $true -SuppressError $true'.
Additionally, you may see the following Warning event logged in the System log:
Description: Request processing failed because the WinRM service cannot load data or event source: DLL="%ExchangeInstallPath%Bin\Microsoft.Exchange.AuthorizationPlugin.dll"
This problem occurs because one of the following conditions is true:
- The ExchangeInstallPath variable is missing.
- The path of the PowerShell virtual directory was modified.
To resolve this problem, use one of the following methods:
- Make sure that the ExchangeInstallPath value is set correctly. To do this, open the System item in Control Panel, click Advanced system settings, and then click Environment variables on the Advanced tab. In the System variables box, locate the ExchangeInstallPath variable. The corresponding value for this variable should be C:\Program Files\Microsoft\Exchange Server\V14\.
- In IIS Manager, locate the entry for the PowerShell virtual directory under Default Web Site. Then, make sure that the entry points to the \Program Files\Microsoft\Exchange Server\v14\ClientAccess\PowerShell folder.
